I feel like it's hard for a series like this to truly be defined as "oversexualized" at any point. I know I can pick out a few characters who fit the bill but the nature of the game just has them coming across as such a parody that I'm not so sure it counts in that way. I mean, I guess it does regardless of the genre of game but the sexualization in this series feels very different from other series that would feature similar characters in different settings, you know?
